SPECIFICATION forming part of Letters Patent No. 739,795, dated September 22, 1903.

Application filed April 19,

To all whom it may 001mm.-

Be it known that I, PETER S. STAUFFER, a citizen of the United States of America, re-' siding at Springfield, in the county of Hampden and Commonwealth of Massachusetts, have invented a new and useful Tall-Register, of which the following is a specification, the same being an improvement on my invention for which Letters Patent No. 679,789

were issued August 6, 1901.

My invention relates to improvements in hot-air wall-registers in which shutters hung in a light frame and provided with cam-slotted ends are employed with operating-slides I 5 having roller-bearings, all as hereinafter fully described, and especially pointed out in the claim; and the objects of my improvement are, first, to provide a register which can be used in a narrow flue as well as in a wide one without unduly obstructing the opening in the same; second, to afford means for positively operating the shutters with ease in either direction in pairs or all together when arrangedin sets of four, as shown, and,third,

to furnish alight, durable, and inexpensive device in the above-mentioned class in which reside the advantages set forth. I attain these objects by the means illustrated in the accompanying drawings, in which- Figure 1 is a front view of the Working end of my register; Fig. 2, a section on lines 2 2, Fig. 1, looking downward in the direction of the arrow, two of the shutters being closed and the other two removed; Fig. 3, a part of 5 a similar section, showing two of the shutters open; Fig. 4, a perspective view of the work ing end of one of the shutters; Fig. 5, a similar view showing-a modified form of construction; Fig. 6, a back view of the register, the

middle being broken out and only two of the shutters showing; and Fig. 7, a top view.

Similar figures refer to similar parts throughout the several views.

A plate 10, which forms the front of the register, has perforations 11 therein, and two oppositely-disposed slotted hangers 12, preferably consisting of angle-irons, are secured to the back of said plate by the screws 13. Shutters 14, provided, by preference,with elevations 15 to register with the plate-perforations 11, are hung back of the plate 10 on rods 16, which have their bearings in the horiparts being such as to said plate.

1502. Serialllc. 108/314. (NomodeL) zontal sides of the hangers and pass through the rolled edges 14 of said shutters. Washers 17 are introduced between the working ends of the shutters 14: hanger. The working endrof each shutter has an extension 18standing at right angles with the same, in which is a suitable cam-slot- 19. I prefer to make the plate, hangers, and shutters of sheet metal in order to secure the desired degree of lightness, and the horizontal side of each hanger is comparatively slight breadthwise in order not to obstruct the dueopening, the construction of the operating permit of this, as will appear hereinafter. Four shutters 14: are shown; but this number is not imperative and may be departed from.

Slides 20 and 20*, having rollers 21 operating in slots 22 in the horizontal side of the adjacent hanger 12, are adapted to be reciprocated against the upper face of said hanger side. Pins 23 extend upwardly from the slides 20 and 20 into the shutter-extension cam-slots 19. 20' and 20" shanks extend forward through slots 24: 24 in the plate 10 and terminate in operating-pieces 25 25, located in front of The slides 20 and 20 are cut away substantially as shown to clear in part at least the slots 22, so as to obstruct the flueopening as little as possible.

Since the shutters 1 1 stand vertically, they can be operated with great ease by means of the pieces 25 at the bottom of the register. If desired, however, the working end of the register may be at the top instead'of at the bottom-that is to say, the register may be turned end for end; but the operation described below will be the same, with the exception of the directions in which the slides move to bring about given results, said directions being opposite to those about tobe described, and the ease of operation will not be impaired. When the slide 20 is actuated to the left, the two shutters 14, connected with said slide, are opened through the medium of the pins 23, which enter the camvslots 19 in the end extensions of said shutters. A reverse movement of the slide 20 closes the before-mentioned shutters again and also closes the other two shutters when open by contacting with the slide '20, which and the adjacent At the outer ends of the slides must have been actuated to the left to open the shutters which are connected with said slide 20. If all of the shutters are to be opened at once, it is only necessary to move the slide 20 to the left, when it contacts with the slide 20. Thus it will be seen that the slide 20 operates to close all of the shutters when open or to open only the shutters connected therewith, and the slide 2O operates to open all of the shutters when closed or to close only the shutters connected therewith. The left-hand ends of the slots 24 limit the movement of the slides 20 and 20 in one direction and determine the extent to which the shutters may be opened; but when said shutters are closed they come to rest against the plate 10. In place of a rod 16 for each shutter 14 said shutter may have a trunnion 143 formed at each end by an extension of the rolled edge 14, as shown in Fig. 5, and this trunnion is received into a hole in the holder. The rods 16 are omitted in this instance; but otherwi e the construction is the same.

As the horizontal part of the lower hanger 12 need be only of sufficient breadth to allow for the roller-slots 22, it is not necessary to make it wide enough to materially obstruct the flue, and the upper hanger may be still narrower or slotted, as shown in Fig. 7. Thus it will be seen that little, if any, obstruction to the free passage of air through the flue is offered by my register. The register construction is otherwise compact and light, as it may well be, because there is no strain brought to bear upon the same. Although the shutters 14 may be placed horizontally, the vertical arrangement is considered to be the better for obvious reasons.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination with a wall-register, of a perforated plate, narrow hangers secured thereto, rods journaledin the hangers, shutters secured to said rods, said shutters having end extensions arranged at right angles to the plane of the shutters, and having slots of like width throughout and arranged at an angle in their intermediate portions and extending at both ends of the angularly-disposed slot in a line parallel with the plane of the shutter anda slide provided with pins to enter said slots and traverse the same, and an operating member attacliedto the slide and projecting beyond the plate, substantially as shown.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
